Thanks again EagleMark. I will start with opening the throttle blades and monitor the IAC counts as you suggest to see if that is why the IAC counts stay at 160 so long.

The car is running the best it ever has since the rebuild and tune. The TPS % is set to zero on every restart with the 8D. I did a little playing around with restarts with partial open throttle and...

Well, I think I finally got to the real root cause of my high idle. I noticed that when the engine was idling high that the TPS percent was not zero. After close examination of my TPS on the BBK...

This is a thread I stated last year when I was having a high idle problem. I thought I got it worked out, but I thought wrong. When I start the car, it idles correctly. After driving it, it starts...

John, Thanks. I am not that familar with acessing the adresses directly. I assume I can edit the XDF file to edit different areas of the bin file. But I have never tried that since I do not know...

The controler is up under the dash. I will see it it is easy to get out and take a look.

Guys, Don't worry, I know how to do it. I'll associate the tables I use. Thanks

I did plot the lockup points on a scatter gram. The unlock table vs TPS % defiantly is a hard limit, but the lock points were all over the place. I have been looking for the min TPS value and haven't...

From my classroom training 30+ years ago, you are correct, this is defiantly too much gain, hence the overshoot. I have thought about the bigger radius on the throttle linkage but haven't wanted to...

That is what it said in the air system service section of my GM Service manual. I agree with you, I don't need it to work, I am just tying to keep it look stock under the hood. Actually I plugged...

I know how to do the associations, I thought I read in the comments in the XDf file that those were already complete. Now that I checked, the couple tables I looked at have none setup.

This may not be the spot for this thread, but it is related to my engine tuning and modifications. My vacuum control cruise worked fine before I built the new engine. Now that I have the new engine...

Yea, I read the service manual and it said it was only active in OPEN loop. But in my case, with a bad valve, it was pumping air into the exhaust manifold all the time. It is now plugged and turned...

JeepsAndGuns, I was reading some comments in the XDF file and I tought you mentioned that you had some of the data tracing already setup. I now have both of your file loaded and I am not getting any...

Thanks Gregs78cam.

OK, I tested the air valve to see if only applies air to the exhaust manifold only during open loop. It turns out to not be functioning correctly at all. The only port that air doesn’t get pumped...

I don't find $8D-1227730-V1.adx. I found 12277730_8D. I assume that is a differant file. Can you give me the correct file?

JeepsandGuns, Excellant work. I will download the ADX file and give it a try. BTW, what is DE? Its not ringing a bell at this time.

My air system has two valves, one pumps air to the converter the other to both exhaust manifolds. If the only time it pumps air the exhaust manifolds is in open loop, I an not going to worry about...

Thanks for the pointer about the DCFO. There are four FCO scalars and flag for TCC lock during DFCO. I think after reviewing the data that the point i made about letting the foot off the gas is...

I did tune with the AIR, EGR,CCP etc. off. Thanks to the advice from EagleMark. Now that all the emissions equipment is turned on, I do see high and low BLMs compaired to what I had tuned to. Now...

I am running the stock tires and I did adjust the TV cable as specified in the GM service manual which is the same as the link you gave me. Thanks for that. The transmission shifts correctly. What I...

I am having the hardest time getting my TCC to function correctly. $8D has one flag, five scalars and four tables to control its function. They all seem to be very straight forward in their function....

On another area related to the O2 sensor. I kept the air injection system on the car. I see a scalar for Air Divert O2 rich/lean reduction in millivolts. Does this offset the point where the EMC...

I got the three wire O2 yesterday. Two wires were black an the other was blue. The two black wires read 15 ohm between each and open to the blue and the O2 case. The blue read open to everything,...
